Description
Technical Field
[0001] This utility model relates to the field of inductor technology, and in particular to an interface bushing for inductor connection wire terminals. Background Technology
[0002] In electric vehicle chargers, inductors are one of the core components, and their performance directly affects charging efficiency, power quality, and system reliability. To ensure the normal use of inductors, bushings need to be added to the terminal interfaces of the connecting wires to ensure connection stability.
[0003] Most current inductor connection wires require the wires to be looped and connected to the terminal interface. This loop structure provides more even pressure distribution and stronger connection stability when fixed with screws, and also creates a larger contact area with the terminal. However, most interface bushing structures are relatively simple, requiring the wires to be looped before being placed at the interface. This may require repeated adjustments to the loop size, making the operation inconvenient and time-consuming.
[0004] Therefore, to address the issue of repeatedly adjusting the coil size of wires during existing interface bushing wiring, an interface bushing for inductor connection terminals can be designed. By using a guide coiling method, the wire can be directly placed at the wiring position before the coiling operation, optimizing the wiring operation steps, ensuring connection stability, saving operation time, and thus effectively enhancing the practical value of the terminal interface bushing. Utility Model Content
[0005] To overcome the problem that most inductor connection terminal bushing structures are relatively simple, requiring the wire to be looped before being placed at the interface, which may require repeated adjustments to the loop size, making the operation inconvenient and time-consuming, this utility model is proposed.
[0006] The technical solution of this utility model is as follows: an interface bushing for inductor connection wire terminals, comprising a base, an inductor body, wire ends, a terminal platform, sleeves, a terminal body, a screw, a pressure plate, an arc-shaped groove, an L-shaped connecting plate, a T-shaped slider, and a guide push plate. The inductor body is arranged above the base, and two sets of wire ends are symmetrically arranged on one side of the inductor body. The terminal platform is arranged above the base, and two sets of sleeves are symmetrically arranged at the top of the terminal platform. The terminal body is arranged on the outer side of the top of the sleeve, and a screw is arranged on the inner side of the sleeve. A pressure plate is arranged at the top of the screw. Two sets of arc-shaped grooves are symmetrically opened at the top of the terminal platform. Two sets of L-shaped connecting plates are symmetrically arranged above the terminal platform. A T-shaped slider is arranged at the bottom of the L-shaped connecting plate, and a guide push plate is arranged at the top of the L-shaped connecting plate.
[0007] Preferably, the inductor body is fixed by setting a base, the terminal body is fixed by using a terminal carrier, the wire end is placed on the terminal body, and the wire end is positioned between the screw and the guide push plate. The guide push plate is positioned by using an arc-shaped groove to define its movement path. The guide push plate is fixedly connected by an L-shaped connecting plate. Pushing the L-shaped connecting plate causes the T-shaped slider to slide along the arc-shaped groove, which in turn drives the guide push plate to push the wire end to circle around the screw. Rotating the screw screw causes the wire end to be screwed into the sleeve, thereby flexibly pressing down the pressure plate. The pressure plate presses the circled wire end tightly onto the terminal body, thus optimizing the wiring operation steps, ensuring connection stability, saving operation time, and enhancing the practical value of the terminal interface bushing.
[0008] Preferably, the screw and the sleeve are connected by a threaded rotation, and an arc-shaped groove is opened on the outside of the sleeve, with the cross-section of the arc-shaped groove set as T-shaped.
[0009] Preferably, the top of the L-shaped connecting plate is fitted to the upper surface of the terminal body, and the T-shaped slider is engaged and slidably connected with the arc-shaped groove.
[0010] Preferably, the top of the terminal carrier is symmetrically provided with two sets of support shells, which are located on the outside of the sleeve column. The top of the support shells is fixedly connected to the bottom of the terminal body, and the top of the pressure plate is provided with an adjusting nut.
[0011] Preferably, an arc-shaped protective plate is provided on the outer side of the pressure plate, and a T-shaped annular groove is opened on the outer side of the pressure plate. An arc-shaped sliding strip is provided at the top of the inner side of the arc-shaped protective plate. The arc-shaped sliding strip has a T-shaped cross section and is slidably connected to the T-shaped annular groove.
[0012] Preferably, two sets of support plates are symmetrically arranged at the top of the base, the inductor body is arranged between the two sets of support plates, the inner side of the support plate is provided with a groove, the two ends of the magnetic core column of the inductor body are provided with mounting plates, the outer side of the mounting plate is provided with positioning posts, the inner side of the groove is provided with positioning slots, and the positioning posts and positioning slots are fitted and connected.
[0013] Preferably, an arc-shaped fixing plate is provided above the mounting plate, a retaining plate is provided at the bottom of the arc-shaped fixing plate, and a retaining groove is provided at the top of the support plate, with the retaining plate engaging with the retaining groove.
[0014] The beneficial effects of this utility model are:
[0015] During wiring, place the inductor body on the base, use the terminal platform to fix the position of the terminal body, place the wire end on the terminal body, so that the wire end is between the screw and the guide push plate, push the L-shaped connecting plate to make the T-shaped slider slide along the arc groove, drive the guide push plate to push the wire end to circle around the screw, and then rotate the screw to screw it into the sleeve, thereby flexibly pressing down the pressure plate, using the pressure plate to press the circled wire end tightly on the terminal body. This solves the problem that most terminal interface bushing structures are relatively simple, and the wire needs to be circled before being placed at the interface, which may require repeated adjustment of the circle size, making the operation inconvenient and wasting operation time, thus enhancing the practical value of the terminal interface bushing.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please see Figure 1 and Figure 2This utility model provides an embodiment: an interface bushing for inductor connection wire terminals, including a base 1, an inductor body 2, wire ends 3, a terminal carrier 4, sleeve posts 5, a terminal body 6, a screw 7, a pressure plate 8, an arc-shaped slide groove 9, an L-shaped connecting plate 10, a T-shaped slider 11, and a guide push plate 12. The inductor body 2 is arranged above the base 1, and two sets of wire ends 3 are symmetrically arranged on one side of the inductor body 2. The terminal carrier 4 is arranged above the base 1, and two sets of sleeve posts 5 are symmetrically arranged at the top of the terminal carrier 4. The terminal body 6 is arranged on the outer side of the top of the sleeve post 5. A screw 7 is provided on the inner side of the terminal block 4, and the screw 7 is threadedly connected to the sleeve 5. A pressure plate 8 is provided at the top of the screw 7. Two sets of arc-shaped grooves 9 are symmetrically opened at the top of the terminal block 4. The arc-shaped grooves 9 are opened on the outer side of the sleeve 5. The cross section of the arc-shaped grooves 9 is T-shaped. Two sets of L-shaped connecting plates 10 are symmetrically arranged above the terminal block 4. The top of the L-shaped connecting plate 10 is attached to the upper surface of the terminal body 6. A T-shaped slider 11 is provided at the bottom of the L-shaped connecting plate 10. The T-shaped slider 11 is engaged and slidably connected with the arc-shaped groove 9. A guide push plate 12 is provided at the top of the L-shaped connecting plate 10.
[0023] Please see Figure 2 and Figure 3 In this embodiment, two sets of support shells 601 are symmetrically arranged on the top of the terminal carrier 4. The support shells 601 are arranged on the outside of the sleeve column 5. The top of the support shells 601 is fixedly connected to the bottom of the terminal body 6. The top of the pressure plate 8 is provided with an adjusting nut 801. The support shells 601 assist in supporting the terminal body 6, ensuring the stability of the terminal body 6. Rotating the adjusting nut 801 drives the screw 7 to rotate, thereby flexibly rotating the screw 7 to adjust the height of the pressure plate 8.
[0024] An arc-shaped protective plate 802 is provided on the outer side of the pressure plate 8. A T-shaped annular groove 803 is opened on the outer side of the pressure plate 8. An arc-shaped slide bar 804 is provided on the top inner side of the arc-shaped protective plate 802. The cross-section of the T-shaped annular groove 803 and the arc-shaped slide bar 804 is T-shaped. The arc-shaped slide bar 804 is fitted and slidably connected with the T-shaped annular groove 803. The coiled position of the wire head 3 passes through the opening of the arc-shaped protective plate 802. The arc-shaped protective plate 802 limits the coiled wire head 3. When the screw 7 is rotated, the arc-shaped slide bar 804 slides in the T-shaped annular groove 803, thereby ensuring that the arc-shaped protective plate 802 always protects the wire head 3 inside, ensuring that the screw 7 can rotate normally up or down.
[0025] Please see Figure 4In this embodiment, two sets of support plates 201 are symmetrically arranged at the top of the base 1. The inductor body 2 is disposed between the two sets of support plates 201. A groove 202 is opened on the inner side of the support plate 201. Mounting plates 203 are provided at both ends of the magnetic core column of the inductor body 2. A positioning post 204 is provided on the outer side of the mounting plate 203. A positioning groove 205 is opened on the inner side of the groove 202. The positioning post 204 and the positioning groove 205 are fitted together. The placement position of the inductor body 2 is determined by the support plate 201, and the installation position of the mounting plate 203 is determined by the groove 202. The mounting plate 203 is placed in the groove 202, so that the positioning post 204 is embedded in the positioning groove 205, thereby limiting and protecting the inductor body 2 and preventing the inductor body 2 from shifting position.
[0026] An arc-shaped fixing plate 206 is provided above the mounting plate 203, and a clamping plate 207 is provided at the bottom end of the arc-shaped fixing plate 206. A slot 208 is provided at the top end of the support plate 201. The clamping plate 207 is engaged with the slot 208. The mounting plate 203 is pressed onto the support plate 201 by the arc-shaped fixing plate 206, and the clamping plate 207 is inserted into the slot 208 to clarify the installation position of the arc-shaped fixing plate 206, thereby stabilizing and fixing the position of the inductor body 2.
[0027] When fixing the inductor body 2, the support plate 201 is fixed by the base 1, and the mounting plates 203 at both ends of the inductor body 2 are placed into the grooves 202 of the support plate 201, so that the positioning post 204 is embedded in the positioning groove 205. Then, the arc-shaped fixing plate 206 is moved to insert the clamping plate 207 into the clamping groove 208, and the inductor body 2 is fixed on the base 1.
[0028] During wiring, the terminal body 6 is supported by the support housing 601 on the terminal platform 4. The wire head 3 is placed on the terminal body 6, so that the wire head 3 is located between the screw 7 and the guide push plate 12. The L-shaped connecting plate 10 is pushed so that the T-shaped slider 11 slides along the arc-shaped slide groove 9, which drives the guide push plate 12 to push the wire head 3 to circle around the screw 7.
[0029] Finally, the adjusting nut 801 drives the screw 7 to rotate downward along the sleeve 5, and the pressing plate 8 presses the coiled wire head 3 tightly onto the terminal body 6. At the same time, the coiled position of the wire head 3 passes through the opening of the arc-shaped protective plate 802. When the adjusting nut 801 is rotated, the arc-shaped slide bar 804 slides in the T-shaped ring groove 803, and the arc-shaped protective plate 802 further limits and protects the coiled wire head 3.
[0030] Through the above steps, the position of the inductor body 2 is fixed by setting the base 1, and the position of the terminal body 6 is fixed by the terminal platform 4. The wire end 3 is placed on the terminal body 6, so that the wire end 3 is located between the screw 7 and the guide push plate 12. The movement path of the guide push plate 12 is defined by the arc-shaped slide groove 9. The guide push plate 12 is fixedly connected by the L-shaped connecting plate 10. Pushing the L-shaped connecting plate 10 causes the T-shaped slider 11 to slide along the arc-shaped slide groove 9, which drives the guide push plate 12 to push the wire end 3 to circle around the screw 7. The screw 7 is rotated to screw it into the sleeve 5, thereby flexibly pressing down the pressure plate 8. The pressure plate 8 is used to press the circled wire end 3 tightly onto the terminal body 6, thereby optimizing the wiring operation steps, ensuring connection stability, and saving operation time.
[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
